Davenport, Iowa – Another fast-moving clipper system is expected to bring accumulating snow to parts of eastern Iowa and northwest Illinois tonight, with hazardous travel conditions developing overnight.
According to the National Weather Service Quad Cities, snow will primarily affect areas north of Interstate 80, where a narrow band of heavier snowfall is forecast to set up. Within this band, 2 to 4 inches of snow is possible, while locations just south of the band may see very little accumulation, creating a sharp gradient over short distances.
Forecasters say snowfall rates could approach 1 inch per hour for a few hours, particularly from Cedar Rapids to Sterling and Rock Falls, Illinois. The heaviest snow is expected between 10 p.m. tonight and 2 a.m. Wednesday, before tapering off toward sunrise.
Winds are expected to increase around daybreak Wednesday, which could lead to drifting snow and brief blowing snow, further reducing visibility. As a result, hazardous travel conditions are possible for the Wednesday morning commute, especially on untreated roads, bridges, and rural highways.
Potential hazards include slippery road surfaces and reduced visibility during heavier snow bursts. The NWS advises drivers to adjust travel plans if possible, slow down, and allow extra time to reach destinations. Commuters, students, and overnight workers traveling early Wednesday should closely monitor road conditions.
Residents are encouraged to keep checking updated forecasts, as small shifts in the snow band could significantly change local impacts.
